I was in a trip to Atlanta and stopped by the South Store last Saturday afternoon. I felt really lucky that several 1903 rifles were still available and picked a 1903A3 with a decent 4-groove barrel and flew back to Minnesota. The armors and clerks are all super nice. I received my rifle via shipping earlier this week. Really love it.

My only question is the big "D" stamp (there are three of them) below the circle P mark at the grip. See picture below. I tried my best to search the information and couldn't find any similar marking. I hope it's not short for "drill rifle"? In addition, there's a smaller "PB" and "3" stamp in front the magazine base (the location of the stamp seems a little weird to me and I'm not sure what kind of stamps are these neither)
